This invention relates -to looms for weaving Vilton pile fabrics and it is the general object of the invention to provide Ymechanism which Awill operate to wrap the pile forming yarn around the pile wire in a continuous coil. v

Such fabrics as lWilton carpets may be woven either on the so-called side wire or stationarypwire loom. In the side wire loom along wire is linserted between the separated planes of weft below the pile forming warp threads but above the dead pile. The wire extends transversely across the fabric and the piles take the form of a sinuous thread running lengthwise ofthe fabric.v In stationary wire looms, on the other hand, thepile wire usually extends through the reed longitudinally of the fabric and itis necessary to effect a crossing-of thepile forming threads from one side to the other of the stationary pile wire. In the usual stationary wire loom the yarn for forming any given tuft will cross the .pile wire twice, moving firstin one direction to form half the tuft and then moving in the other direction to formjthe other half of the tuft. A

It is necessary that the yarn be drawn from thegsameside of the stationary pile wire by the jacquard when selected to form pile and it is this fact which requires the double crossing of the yarn. For instance, the yarn may rise on'the left hand side of the pile wire and be crossed over in a right hand direction and down on the right hand side of the pile wire.` rpiclr of filling is then laid over the actiye pile yarn and under. the pile wire. If the operationof forming the pile stopped at this point theactive pile yarn would be in the wrong position to be lifted at asub-v sequent call and it is for this reason that the piles must be crossed again, going 'from the right to the left hand side of the pile wire over the 4latter and then depressed so that a second pick of filling may be inserted over the active pile and under the pile wire. This double operation leaves the pile yarn in proper position to be raised when .called again. VIt will be understood that for the formation of each pile therefore it is necessary for the active pile forming yarn to cross the pile wire twice and in order that this result may be accomplished it is customary to have the pile yarn of half the size of that employed in side wire looms where a single crossing of the transverse pile wire is sufficient to form the pile and where the necessity for kplacing the pile yarn on the right side of the pile wire does not arise. i

It is an important object of my present invention to provide means for looping the active pile around the pilewire in the form of continuous coil so that a single move# ment of the pile yarn from the left side of the wire over the latter and down on the right hand side of the pile wire will be. suf?- cient to form a complete loop or pile, the pile yarn being restored to its proper position on the correct side of the pile wire by a single revolution around the latter. In this way I am enabled to produce a complete pile with a single .passing of the yarn and therefore much more quickly than is possible in present methods.

It is a further object of my present inven tion to provide on the hand rail of the lay a laterally moving reed effective to move the pilevyarn from one side to the other of the pile wire and then to return the pile forming yarn to its original position while under the pile wire.

Tit-h these and other objects in view which will appear as the description proceeds my invention resides in the combination and arrangement of parts hcreina fter described and set forth in the claims.

Referring particularly to Fig. 1, I have shown afloomvfraine and a lay 11 mov- `able back and'forth in the loom frain'earound an airis12.y The loom has a breastbeam 13 ywith a cross bar 14 to hold pile wires 15 in positionfl ydo not wishto'be limitedstov any particular forniY of pile wire but it is desir-y able to have some: form ofv cutter indicated l at 16 integral with the pile wire and eifecoperation.`

tive to cut the loops of pile yarn which extend over the pile wire during the weaving The pile wire has a .rearwardly extending portion 17 which is preferably inclined up'- wardly as set forth vin Fig. 1. t is to be understood thatfthere are` a set of pile wires( extending across the loom, one preferably for each reed space` and the'forward ends of saidA 'pilewires are held in Vposition rigidly against displacement in the direction lof the .length ofthe fabric beingwoven as well as laterally thereof; l j

The lay is provided with'areed 18v and a i hand rail 19 secured to the lay in any api proved mannerlandmoving back and forth withthe latter: As shown in Figs. 1 and 2 the Vhand railis provided with guides 2O in which movesa raclr member' 21 in a direc-VY tion parallel'to the length'of 'the hand rail. Said member isconiined to the guide Vmenibers 2O by-'gib 22 andthefraclrl is providedY Vwith `teeth 28- at one end thereof tomesh with a pinion 24.

The cam-is provided with two highv surfacesl 40 .between which Y are located .felatively low surface'Sl;

Binder coninin'gvvv 'devices'. in' the forni 'i of heddles 42 are provided with elongated eyes 43 which are held vertical by means of lingoes 44. The heddles are connected at their upper ends to fixed supports 45 and are capa# ble of slight lateral movement with vrespect to the reed. The eye 48fof each heddle 42 has passing therethrough a pair of binder threads B and it is to be understood that therey will be oneheddle eye foreach reed space, each of the latter `being -occupied by two binders.

- The rearward n extension 17 of eachY pile wire is provided with an upstanding arm 46 the upper end of. which projectsvabove a line passing throughtlie fell of the cloth and the lowery e'ndof the corresponding finger $28 on A the rack 21.

vIn Vtheeperation ofl my invention the se lectedpile yarn P which is to form the surface'of the finished fabric will be raised by' the jacquard not shown `to the point indi# cated'in Fig. 1 above Vthe lower ends of the lingers 28 and the arms 46.* The Vdriving mechanism for the shaftp2'5 will'be'so timed that the rack 21 will be given a movement to' raised". They fingers 28 willy therefore engage the active pile yarns and move thel saine from the left to the right hand side ofthe pile wire` as viewed in Fig. 2. Thel acquardV will then operate to lower the active-pile yarn and the latterV will pass below the tops of the arms 46 before they are Vreleased ybyy the fingers 28,

the: right after' the pile yarn P has' been y the arms 46 operating in this way to insurel movement of the pile'V yarn down on hand side ofthe pilewire. f

4As soon a'stl'ieactivepile yarnmQves toa position below Vthe lingers 28* it will tend by its elasticityv vto move vloaclrto its normal lpo'-,V sition whi'chis to thelefthandside kof the pile wire. The arms 46, however, willre- 'strain this` movement until; the active pile llVhen a changein the active pile is'to occur thepile'formingl yarn which is to bev retired will upon moving` down below the pilewire '1 spring back to'the leftof the pilen wirein the Vusual manner and jwill then become dead or beburied inthe fabric, :and another ofthe color yarns which is to .become activepile willbey raised jfromthe left' handside of the n fingersf28 pile wire to be acted upon bythe vinthe manner already 4descr'bz-id.- 'i 1 Y 'Hite-*binder threads B may @manipulated the' right in the usual manner and are placed in the heddles 43 so as not to become entangled with the active pile yarn when the latter is being looped around the pile wire.

From the foregoing it will be seen that I have provided mechanism for wrapping each active pile yarn around its corresponding pile wire in the form of a coil-so that a single crossing over the top of the pile Wire is sufficient to form a complete tuft. It will also be seen that this control of the active pile is facilitated by the rack and fingers 28 which move on the hand rail, said fingers acting to move the pile yarn from their normal posie tionon one side of the pile wire to a position on the other side of the pile wire. The beveled segment moves about a point which is very close to the axis of the lay so that the rocking of the lay back and forth has very little if any effect on the movement of the rack with respect to the hand rail. Any movement which may result on the part of the rack incident tothe normal operation of the lay may be corrected by properly forming the surface of the cam which rocks the bevel segment. I-Iaving thus described my invention it will be seen that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is: y

1. In a pile fabric loom, a stationary pile f Wire extending longitudinally of the fabric being woven and having a free rearend, a lay having a hand rail, a rac-k movable along the hand rail, fingers movable with the rack to engage the active pile yarn, means to move the rack laterally with respect to the lay to shift the active pile yarn from one side to the other side of the pile wire, said fingers being of such length that as the active pile yarn moves ydownwardly it will pass out of control of the fingers and when below the pile wire be free to move back to its original position.

' 2.' In a pile. fabric loom, a lay movable therein, a stationary reed mounted on and movable with the lay, a normally stationary pile wire extending through the reed and Ahaving an upturned portionV at the rear end thereof, and an auxiliary reed movable rela- ,tively to the stationary reed and having a i portion thereof lying below a line passing through the fell of the fabric and the upturned rear end of the pile wire, said auxil- "iary reed lying between the stationary reed and the upturned end of the pile wire.

3. In a pile fabric lo-om having a lay, a

- stationary reed mounted on and movable with the lay, a handrail supported by the lay, an auxiliary reed normally stationary but movable transversely of the movement of the lay and the first named reed and mounted on they handrail behind said first named reed, a

normally stationary pile wire around which the pile is woven, said wire having a portion extending rearwardly through the stationary reed and beyond the auxiliary reed, said rearwardly extending end of the pile wire having an upturned portion to guide the pile yarn as the latter is woven over the pile wire.

4L. In a pile fabric loom having a lay, a pile wire around which the pile yarn is woven, said lay having a stationary reed through which the pile wire extends, a hand rail supported by the lay and having an auxiliary reed mounted for a transverse movement thereon, a rack and pinion to move the auxiliary reed, a segment and gear to give movements to the rack and pinion, connections between the segment and gear, and rack and pinion, means to give the segment and gear an oscillating movement, said movement of the segment being transmitted through the connections to the rack and pinion to give the second reed its transverse movement.

5. Ina pile fabric loom, a lay movable back and forth therein, a reed secured to said lay and held against movement laterally of the lay, a second auxiliary reed mounted on the lay and capable of lateral movement relatively to the lay and first named reed, said auxiliary reed located behind the first named reed, and a pile wire extending from the front of the lay through the first reed and terminating behind the auxiliary reed, said pile wire having an arm rearwardly of the auxiliary reed, and the latter moving to move a pile warp from one side to the other of said arm.

6. In a pile fabric loom having binder threads and pile yarn, a lay having a stationary reed thereon, a hand rail supported by the lay, an auxiliary reed mounted on the hand rail behind the stationary reed to have a movement transverse of the movement of the lay, a normally stationary pile wire extending through the reed and having at its rear end an upturned portion to guide the pile yarn, transverse movement of the auxiliary reed moving vthe pile yarn from one side of the pile wire to the other, and a device independent of the lay and reed and through which the binder threads extend and are lkept from becoming entangled with the pile
